4.4.3 Mounting orientation and forces
1. The actuator can be mounted in any orientation and handle both pushing and pulling loads.
2. Always install actuator so that the force of the load acts in the center of the extension tube and the
rear adapter.
3. Only mount the actuator to the rear and front adapter mounting holes.
4. Only use solid mounting pins and support them at both ends.
5. The mounting pins must be parallel to each other both radially and axially.

4.4.4 Cable connector cover plate
1. The cover plate is held in place by a screw (M2.5 with Torx T8 head) that can be accessed through
the hole in the top of the cover plate (a). Keep in mind to mount the actuator so that there is enough
clearance to access the screw with a tool!
2. Once the cover plate is released it needs to be pushed about 20 mm (0.8 inch) in the direction of
the arrow symbol on the cover plate before it can be removed from the actuator (b). The connectors
are a part of the backside of the cover plate and can be accessed once the cover plate is removed.
3. Make sure to put the cover plate back correctly and torque the screw to 0.45 Nm (4 in-lb) to ensure
that the actuator cover plate and connectors are properly sealed.
